(not complete) integration of peggi for html conversion
clean up lst.vim, move functions around

no actual change in behavior or so
Indent after colon only if at end of line

because there are problems otherwise
Fix cursor misplacement after CR in front of space
More functions moved around
fold also multiline items (folding is still slow)
When pressing S-Tab, always jump to prev link

not to the start of the link the cursor is on
g:vimwiki_listsyms is a string again, not a list

this is to be backwards compatible
we still need to split it into a list internally, because indexing
doesn't work for unicode symbols
Some more small cleanups
Fix CR not working in one circumstance
Finally introduce commands for all list keys

and update the documentation
Cleanup of the documentation. Mostly superfluous whitespaces
